`TIRE HEATER.

Application filed November 4, 1925. Serial No. 66,875.k

This invention relates to a device for hea-ting the metal rims'or tires of Wagon wheels. lt is an object of the present invention to provide a heater for the metal rims or tires' of wagon wheels so that the rims will be eX- panded a predetermined degree for the ap.- plication of the rims to the Wheels.

A further object of the invention is the provision of a circular stove equipped with a plurality `of oil burners for y.supplying the heat at predetermined points with a removable metal cover of conical shape and provided with a chimney at its center for the escape of the gases.

This inventiony Will be best understood from a consideration o'f the following` detailed description, in View of the accompanying drawings forming a part of the speciiica-4 tion; nevertheless it is to be understood that the invention is not confined to the disclosure, being susceptible of such changes and modifications Which shall define no material departure from the salient features of the invention as expressed in the appended claim.

In the drawings:

Figure 1 is a plan View of the heater.

Figure 2 is a vertical section of the same.

Figure 3 is a fragmentary vertical View in section of the heater'showing the position of the oil burners.

Figure 4 is a side view of the heater with the operating means for the removable cover shown :in perspective.

Referring more particularly to the drawings designates a brick AWall having an interior coating 11 of concrete and also an exterior coating 12 of the same material. A metal ring 13 is mounted on the top of the wall and has an inner Hange 14 and an outer flange 15 Welded or secured in any approved manner at its opposite peripheries.

Mounted on the ring 13 is a conically shaped cover 16 which is reinforced adjacent its periphery by polygonally Shaped angle iron construction 17. The cover has an annular flange 18 riveted thereto which is adapted to seat on the ring 13. A U-shaped hand piece 19 is secured to the front end of the cover. Straps 20 are riveted to the cover at its rear end and provided With eyes 21 adapted to receive a bolt 22 mounted in bearings 23 which are secured to the ring 13.

They bearings are provided with depending extensions shown in dotted lines at 24 in Figure 2 which are cemented into the brick Wall 10. v i

1t will be noted that the flange 18 at its end and adjacent; the hinges is cut away as shown at 25 so that the bearings for Athe strap hinges may be properly positioned on the ring 13. The rear end ot the polygoi'rally shaped reinforcing member 17 is also cuty away at the rear for the positioning of the strap hinges 20.

The center of the dome or eonically shaped cover 16 is vprovided 'with a passage yin which is tightly fitted an exhaust pipe 2G which has its outer end projecting above the cover and its inner end, as shown at 2T projecting partially into the furnace or stove. This pipe 26 provides a flue for the escape of the gases formed by the plurality of burners located at spaced points around the Wall 10.

The Wall .at three spaced` points and at 1200 apart is provided with radial slots 29 to receive a nozzle 30 of an oil burner 31.

The burner is supplied with oil through a pipe 32 and air through a pipe 33 which are controlled respectively by the valves 34 and 35. The side Walls ofthe burner are reinforced by metal plates 36 which are welded to the ring 13 and the segments of the rings 14 .and 15.

A post 37 has its lower end firmly imbedded in the Wall 10 at the rear of the stove and is of suiicient height for providing cables and pulleys for lifting the cover 1G for the insertion or removal of the rims, a. pulley y38 is connected with Athe U-slu-pedv member 19 through which is trained a cable 39. One end of the cable is secured as at 40 to the upper free end of the post 37, the other end of the cable being trained overa pulley 41 and brought downwardly and trained over a pulley 42 and connected with a Windlass 43. This Windlass is rigid with a shaft which carries a gear 44. A second gear 45 is mounted on the shaft adapted to be operated by a removable crank (not shown) Which is adapted to engage the finished end 46 of the operating shaft. The Windlass and operating mechanism for the Windlass are mounted in a frame 47 which may be located at any convenient position from the stove so that when the Windlass is rotated in one direction the cover 16 Will be elevated and when released the Weight of the cover will cause a reverse operation of the Windlass and its operating mechanism. Any form of breaking means may be employed or the operating` shaft ot the gear 45 may be manually controlled for permitting the cover to be lowered at any rate desired.

After the cover has been raised as shown in Figure et by the Windlass @t3 the rims are placed inside ot' the furnace and the oil burners are lighted. The cover is then closed for a predetermined length of time or until such time as the rims are properly heated and expanded YIfor applying them to the fellies ol Wagon Wheels. rlhe Substantially closed furnace or stove provides Vfor a ready heating of the rims and due to the tact that the rims are heated at a number ot points together with the air in the stove, the rims after a certain time will be uniformly heated throughout and thereby uniformly expanded.

At the end ot the time the burners are turned off and the cover is raised for the removal ot the rims whence another series o rims may he placed in the furnace and heated as before.

.Vhat I claim is:

A tire heating apparatus comprising an annular brick Wall provided with a hingedly mounted cover adapted to term with the brick Wall a heating chamber ttor tires, said Wall being provided with spaced radial passages, a concrete liner formed on the bottom and inner Wall of the chamber, a metal ring located on the top of the back Wall and having a depending annular flange embracing the outer tace of the Wall and an annular depending flange embracing the inner ilace of the wall, the depending tlanges and the liners being provided with slots aligned with the radial passages of the wall, vertically disposed metal ilanges depending Yfrom the ring and secured to the annular [langes and spaced from each other in the radial passages, and a burner disposed in each passage and projecting through the spaced vertical flanges, said burner terminating short of the inner end ot the passages, and a llue connected with the cover.
